PAC Lithium Ion Rechargeable Battery

PAC Battery 18650 12v lithium ion pack 3.5Ah high capacity for medical device

1. This specification describes the basic performance, technical requirement, testing method, warning and caution of the Li- ion Cylindrical rechargeable battery .The specification only applies to PAC Technology Co.,Ltd.
Because batteries utilize a chemical reaction, battery performance will deteriorate over time even if stored for a long period of time without being used. In addition, if the various usage conditions such as charge, discharge, ambient temperature, etc. are not maintained within the specified ranges the life expectancy of the battery may be shortened or the device in which the battery is used may be damaged by electrolyte leakage. If the batteries cannot maintain a charge for long periods of time, even when they are charged correctly, this may indicate it is time to change the battery.

2.0.2C capacity testing of 12v 18650 lithium battery pack
After standard charging, rest battery for 10min, then discharging at 0.2C to voltage 3.0V, recording the discharging time.
3. Cycle life testing of 12v 3.5Ah lithium battery pack
Constant current 0.5C charge to 4.2V, then constant voltage charge to current declines to 0.01C, rest 10min,constant current 0.5C discharge to 3.0V, rest 10min. Repeat above steps till continuously discharging capacity Higher than 80% of the Initial Capacities of the Cells.

5. Lithium ion Battery operation instruction

5.1 Charging

  • Charging current: Cannot surpass the biggest charging current which in this specification book stipulated.
  • Charging voltage: Does not have to surpass the highest amount which in this specification book stipulated to decide the voltage.
  • Charge temperature: The battery must carry on the charge in the ambient temperature scope which this specification book stipulated.
  • Uses the constant electric current and the constant voltage way charge, the prohibition reverse charges. If the battery positive electrode and the cathode meet instead, can damage the battery.

5.2 Discharging current

  • The discharging current does not have to surpass this specification book stipulation the biggest discharging current, the oversized electric current electric discharge can cause the battery capacity play to reduce and to cause the battery heat.

5.3 Electric discharge temperature

  • The battery discharge must carry on in the ambient temperature scope which this specification book stipulated.

5.4 Over-discharges

  • After the short time excessively discharges charges immediately cannot affect the use, but the long time excessively discharges can cause the battery the performance, battery function losing. The battery long-term has not used, has the possibility to be able to be at because of its automatic flashover characteristic certain excessively discharges the condition, for prevented excessively discharges the occurrence, the battery should maintain the certain electric quantity.

5.5 Storing the Batteries

  • The battery should store in the product specification book stipulation temperature range. If has surpasses above for six months the long time storage, suggested you should carry on additional charge to the battery
6. Delivery of PAC battery pack

• By Air Door to Door Service

• By Sea Door to Door Service

• By Express: EMS, TNT, UPS, FedEx
